To provide a sheave for an elevator capable of lightening the weight of the sheave and suppressing the abrasion of an outer peripheral part of the sheave due to contact with a rope.SOLUTION: A sheave for an elevator includes an outer ring part in which a rope is wound around its outer peripheral part and an inner ring part whose outer peripheral part is covered with the outer ring part. The density of the inner ring part is smaller than the density of the outer ring part. The hardness of the outer ring part is larger than the hardness of the inner ring part.SELECTED DRAWING: Figure 2
